NICA-SPD. The following subjects are under consideration for both detectors: ► Polarization effects in heavy ion collisions using spin dependent observables in multi-particle production reactions ► Nucleon spin structure via DY and J/Ψ production processes and others. NICA-SPIN 2013, Dubna
NICA-SPD. Polarization effects in heavy ions collisions with MPD and SPD Proposed for consideration The following polarization observables at NICA can be studied with MPD &SPD: • MMT-DY studies; • Λ Polarization as a probe of isotropic matter formation; • Correlations of Λ polarization with charge separation as a complementary signal for CP-violation in dense matter , • Transverse handedness as a probe for collective orbital momentum of the matter, • Tensor polarization of dileptons as a complementary probe of matter formation, dilepton production mechanisms and collective orbital momentum.

Extraction of unknown (poor known) parton distribution functions (PDFs): Boer-Mulders PDF Sivers PDFs (Efremov,… PLB 612 (2005), PRD 73(2006)); Transversity PDF (Anselmino, Efremov, …) Transversity and first moment of Boer-Mulders PFDs (Sissakian, Shevchenko, Nagaytsev , Ivanov, PRD 72(2005), EPJ C46 ,2006 C59, 2009) Longitudinally polarized sea and strange PDFs andtenzor deuteron structure (Teryaev, …) The same PDFs from J/y production processes ( ).

NICA-SPD. Estimations were done for 1 month of data taking. For 3 years of data taking: we expect to take ~100K DY events. (in table, graphs Mll>2 GeV) MC simulation for the feasibility studies of DY polarized processes The SSA asymmetries. Top:access to transversity and Boer-Mulders PDFs. (Sissakian, Shevchenko, Nagaytsev,PRD 72 (2005), EPJ C46 (2006)) Bottom: access to Sivers PDFs (Efremov,… PLB 612(2005), PRD 73(2006)); Alsymmetries are estimated for 100 K DY events A.N.
